Usage

Either

src/main.c

#include "mgos.h"
#include "mgos_ir.h"

static void irrecv_cb(int code, void *arg)
{
  LOG(LL_INFO, ("IR: %08X", code));
  (void) arg;
}

enum mgos_app_init_result mgos_app_init(void)
{
  // TSOP on pin 14, NEC protocol
  mgos_irrecv_nec_create(14, irrecv_cb, NULL);

  return MGOS_APP_INIT_SUCCESS;
}

or

fs/init.js

load("api_ir.js");

// TSOP on pin 14, NEC protocol
let ir = IR.Receiver.NEC.create(14, function(code) {
    print("IR", code);
}, null);

mgos_irrecv_nec_create

struct mgos_irrecv_nec_s *mgos_irrecv_nec_create(
  int pin,
  void (*cb)(int, void *),
  void *userdata
);

Create an object instance of IR receiver for NEC protocol. Return value: an object with the methods described below.

mgos_irrecv_nec_close

void mgos_irrecv_nec_close(struct mgos_irrecv_nec_s *obj);

Destroy an object instance of IR receiver for NEC protocol.

mgos_irsend_nec

void mgos_irsend_nec(int pin, int code, bool tsop);

Send IR code for NEC protocol. Params: pin: GPIO number. code: 32-bit code. tsop: mode: true - mimic TSOP signal, false - drive real IR led at 38 kHz.

myIR.close

myIR.close()

Close receiver handle. Return value: none.

IR.Sender.NEC.pwm

IR.Sender.NEC.pwm(pin, code)

Send NEC IR code via real IR led. Return value: none.

IR.Sender.NEC.tsop

IR.Sender.NEC.tsop(pin, code)
